2008 VOLVO V70 oil temperature

If this light comes on while the vehicle is being driven, or remains on for longer than approximately 10 seconds after
the vehicle has been started, the SRS system's diagnostic functions have detected a fault in a seat belt lock or
pretensioner, a front airbag, side impact airbag, and/or an inflatable curtain. Have the system(s) inspected by a trained
and qualified Volvo service technician as soon as possible.
Seat belt reminder
This symbol comes on for approximately 6 seconds if the driver has not fastened his or her seat belt.
Generator not charging
This symbol comes on during driving if a fault has occurred in the electrical system. Contact an authorized Volvo
workshop.
Engine temperature
Engine overheating can result from low oil or coolant levels, towing or hard driving at high heat and altitude, or
mechanical malfunction. Engine overheating will be signaled with text and a red warning triangle in the middle of the
instrument display. The exact text will depend on the degree of overheating. It may range from " HIGH ENGINE
TEMP - SLOW DOWN " to "HIGH ENGINE TEMP - STOP ENGINE ." If appropriate, other messages, such as
" COOLANT LEVEL LOW " will also be displayed. If your engine does overheat so that you must stop the engine,
always allow the engine to cool before attempting to check oil and coolant levels.
Fault in brake system
If this symbol lights, the brake fluid level may be too low. Stop the vehicle in a safe place and check the level in the
brake fluid reservoir, see page 223
. If the level in the reservoir is below MIN , the vehicle should be transported to an
authorized Volvo workshop to have the brake system checked.
If the brake and ABS symbols come on at the same time, there may be a fault in the brake force distribution system.
1. Stop the vehicle in a safe place and turn off the engine.
2. Restart the engine.
If both symbols extinguish, continue driving.
If the symbols remain on, check the level in the brake fluid reservoir. See page 223. If the brake fluid level is
normal but the symbols are still lit, the vehicle can be driven, with great care, to an authorized Volvo workshop to
have the brake system checked.
If the level in the reservoir is below MIN , the vehicle should be transported to an authorized Volvo workshop to
have the brake system checked.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a warning message is displayed in the text window:
DO NOT DRIVE. Have the vehicle towed to an authorized Volvo retailer and have the brake system inspected.
If the ABS and Brake system lights are on at the same time, there is a risk of reduced vehicle stability.

Keylock: Your vehicle is equipped with a keylock system. When the engine is switched off, the gear selector must
be in the Park position before the key can be removed
2 from the ignition slot.
1If the gear selector is in the D or R positions and the car is not moving, engine speed (rpm) will be lower and it will take longer for the engine to
reach normal operating temperature.
2Does not apply to vehicles with the optional keyless drive.
CAUTION
When starting in cold weather, the automatic transmission may shift up at slightly higher engine speeds than
normal until the automatic transmission fluid reaches normal operating temperature.
Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough
to prevent engine damage.
The engine should be idling when you move the gear selector. Never accelerate until after you feel the
transmission engage. Accelerating immediately after selecting a gear will cause harsh engagement and premature
transmission wear.
Selecting P or N when idling at a standstill for prolonged periods of time will help prevent overheating of the

Sensor location
The sunlight sensor is located on the top side of the dashboard.
NOTE
The sunlight sensor monitors which side of the car that is most exposed to sunlight. This can mean that the
temperature may differ between the right and left-side air vents, even if the temperatures set for both sides of the
passenger compartment are the same.
The temperature sensor for the passenger compartment is located below the climate control panel.
The outside temperature sensor is located on the door mirror.
The humidity sensor (option) is located in the interior rearview mirror.
NOTE
Do not cover or block the sensors with clothing or other objects.
Side windows and moonroof
To ensure that the air conditioning works optimally, the side windows, and the optional moonroof should be closed.
Fog on the inside of the windows
The defroster function should be used to remove fog or mist from the inside of the windows. Keeping the windows
clean with a commercially available window washing spray will also help prevent fogging or misting.
Vents in the parcel shelf
NOTE
The air vents at the rear of the parcel shelf should never be obstructed.
Temporary shut-off of the air conditioning
The air conditioning is momentarily disengaged during full-throttle acceleration or when driving uphill with a trailer.
This may result in a temporary increase in cabin temperature.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Climate system maintenance
Special tools and equipment are required to maintain and carry out repairs on the climate system. Work of this type
should only be done by a trained and qualified Volvo service technician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a.
This substance

Water or mud can make the brake linings slippery, resulting in delayed braking effect.
CAUTION
Engine damage will occur if water is drawn into the air cleaner.
If the vehicle is driven through water deeper than 9 in (25 cm), water may enter the differential and the
transmission. This reduces the oil's lubricating capacity and may shorten the service life of these components.
Do not allow the vehicle to stand in water up to the door sills longer than absolutely necessary. This could result
in electrical malfunctions.
If the engine has been stopped while the vehicle is in water, do not attempt to restart it. Have the vehicle towed
out of the water.
Engine and cooling system
Under special conditions, for example when driving in hilly terrain, extreme heat or with heavy loads, there is a risk
that the engine and cooling system will overheat. Proceed as follows to avoid overheating the engine.
Maintain a low speed when driving with a trailer up long, steep hills.
Do not turn the engine off immediately when stopping after a hard drive.
WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off.
Remove any auxiliary lights from in front of the grille when driving in hot weather conditions.
Do not exceed engine speeds of 4500 rpm if driving with a trailer in hilly terrain. The oil temperature could become
too high.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
When the engine is not running, avoid using ignition mode II . Many electrical systems (the audio system, the
optional navigation system, power windows, etc) will function in ignition modes 0 and I . These modes reduce drain on
the battery.
Please keep in mind that using systems, accessories, etc., that consume a great deal of current when the engine is not
running could result in the battery being completely drained.
The optional 12 volt socket in the cargo area provides electrical current even with the ignition switched off, which
drains the battery.

Driving recommendations
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo service technician before
driving long distances. Your retailer will also be able to supply you with bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.
As a minimum, the following items should be checked before any long trip:
Check that engine runs smoothly and that fuel consumption is normal.
Check for fuel, oil, and fluid leakage
Have the transmission oil level checked.
ProCarManuals.com

Check condition of drive belts.
Check state of the battery's charge.
Examine tires carefully (the spare tire as well), and replace those that are worn. Check tire pressures.
The brakes, front wheel alignment, and steering gear should be checked by a trained and qualified Volvo service
technician only.
Check all lights, including high beams.
Reflective warning triangles are legally required in some states/provinces.
Have a word with a trained and qualified Volvo service technician if you intend to drive in countries where it may
be difficult to obtain the correct fuel.
Consider your destination. If you will be driving through an area where snow or ice are likely to occur, consider
snow tires.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting:
Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection.
This gives protection against freezing down to - 31°F (-35°C). The use of "recycled" antifreeze is not approved by
Volvo. Different types of antifreeze must not be mixed.
Volvo recommends using only genuine Volvo antifreeze in your vehicle's radiator.
Try to keep the fuel tank well filled - this helps prevent the formation of condensation in the tank. In addition, in
extremely cold weather conditions it is worthwhile to add fuel line de -icer before refueling.
The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weather starting as
well as decreasing fuel consumption while the engine is warming up. For winter use, 5W -30 oil, particularly the
synthetic type, is recommended. Be sure to use good quality oil but do not use cold-weather oil for hard driving or in
warm weather. See page 276
for more information on engine oil.
NOTE
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge.
The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc. are used more
often. Moreover, the capacity of the battery decreases as the temperature drops. In very cold weather, a poorly charged
battery can freeze and be damaged. It is therefore advisable to check the state of charge more frequently and spray an
anti-rust oil on the battery posts.
Volvo recommends the use of snow tires on all four wheels for winter driving. See the information on page 259.
To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze. This is important
since dirt is often splashed on the windshield during winter driving, requiring the frequent use of the washers and
wipers. Volvo Washer Solvent should be diluted as follows: Down to 14° F (-10° C): 1 part washer solvent and 4 parts
water Down to 5° F (-15° C):
195 05 During your trip
Driving recommendations
1 part washer solvent and 3 parts water Down to 0° F (-18° C): 1 part washer solvent and 2 parts water Down to -18°
F (-28° C): 1 part washer solvent and 1 part water.
Use Volvo Teflon Lock Spray in the locks.
Avoid using de -icing sprays as they can cause damage to the locks.

Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.
NOTE
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge. Please consult your Volvo retailer.
226 06 Maintenance and specifications
Fluids
Coolant
Normally, the coolant does not need to be changed. If the system must be drained, consult a trained and qualified
Volvo service technician.
See page 279
for information on cooling system capacities.
CAUTION
Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has a
lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water and antifreeze).
The cooling system must always be kept filled to the correct level, and the level must be between the MIN and
MAX marks. If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Different types of antifreeze/coolant may not be mixed. Check coolant regularly.
WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools.
If it is necessary to top off the coolant when the engine is warm, unscrew the expansion tank cap slowly so that
the overpressure dissipates.

Engine oil must meet the minimum ILSAC specification GF-3, API SL, or ACEA A1/B1. Lower quality oils may not
offer the same fuel economy, engine performance, or engine protection.
Volvo recommends Castrol.
Depending on your driving habits, premium or synthetic oils may provide superior fuel economy and engine
protection. Consult your Volvo retailer for recommendations on premium or synthetic oils.
Oil additives must not be used.
Synthetic oil is not used when the oil is changed at the normal maintenance services. This oil is only used at customer
request, at additional charge. Please consult your Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 104° F (40° C) in your area, Volvo recommends, for the protection of your engine, that you
use a heavier weight oil, such as such as SAE 5W -40 or 0W -40. See the viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when temperatures do not exceed 104° F (40° C),
SAE 5W -30 will provide good fuel economy and engine protection. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 0W -30 or 0W -40 and complying with oil quality requirements are recommended for
driving in areas of sustained temperature extremes (hot or cold), when towing a trailer over long distances, and for
prolonged driving in mountainous areas.
